Abecarnil (ZK 112119) is a ligand or a partial agonist for benzodiazepine (BZ) receptor. Abecarnil can act as a positive allosteric modulator of GABAA receptor. Abecarnil inhibits the binding of the BZ [3H]lormetazepam to rat cerebral cortex membranes, with an IC50 of 0.82 nM.

In Vitro Activity
In vitro, abecarnil inhibited the binding of the BZ [3H]lormetazepam to rat cerebral cortex membranes with an IC50 value of 0.82 nM in comparison to 56 nM for DZP.

In Vivo Activity
Abecarnil, a selective benzodiazepine receptor agonist with marked anticonvulsant activity, was administered together with chronic PTZ to evaluate whether persistent activation of GABAA receptors and suppression of seizures during kindling might affect the sensitivity of septohippocampal cholinergic neurons to a challenge dose of PTZ. Abecarnil (1 mg/kg, i.p.) administered 40 min before each PTZ injection neither antagonized the decrease in basal acetylcholine release (2.26 +/- 0.19 pmol per 20-min sample) nor prevented the development of kindling. In contrast, abecarnil prevented the chronic PTZ-induced increase in the sensitivity of acetylcholine release to a challenge dose of PTZ.
